Particularly important in the production of fruit from plants is thebeginning stage of growth where the plant emerges and matures intoestablishment. A method of treating a seed, seedling, or plant todirectly improve the germination, emergence, and maturation of theplant; or to indirectly enhance the microbial soil community surroundingthe seed or seedling is therefore valuable starting the plant on thepath to marketable production. The standard typically used for assessingemergence is the achievement of the hypocotyl stage, where a stem isvisibly protruding from the soil. The standard typically used forassessing maturation is the achievement of the cotyledon stage, wheretwo leaves visibly form on the emerged stem. Some botanists view thebeginning of maturation as starting at when the first true leaf emergesbeyond the cotyledon stage, as the cotyledons are already pre-formed inthe seed prior to germination. Some botanists see maturation as a longphase that proceeds until full reproductive potential has been achieved.

Important in the production of fruit from plants is the yield andquality of fruit, which can be quantified as the number, weight, color,firmness, ripeness, sweetness, moisture, degree of insect infestation,degree of disease or rot, degree of sunburn of the fruit. A method oftreating a plant to directly improve the characteristics of the plant,or to indirectly enhance the chlorophyll level of the plant forphotosynthetic capabilities and health of the plant's leaves, roots, andshoot to enable robust production of fruit is therefore valuable inincreasing the efficiency of marketable production. Marketable andunmarketable designations can apply to both the plant and fruit, and canbe defined differently based on the end use of the product, such as butnot limited to, fresh market produce and processing for inclusion as aningredient in a composition. The marketable determination can assesssuch qualities as, but not limited to, color, insect damage, blossom endrot, softness, and sunburn. The term “total production” can incorporateboth marketable and unmarketable plants and fruit. The ratio ofmarketable plants or fruit to unmarketable plants or fruit can bereferred to as “utilization” and expressed as a percentage. Theutilization can be used as an indicator of the efficiency of theagricultural process as it shows the successful production of marketableplants or fruit, which will be obtain the highest financial return forthe grower, whereas total production will not provide such anindication.

To achieve such improvements in emergence, maturation, and yield ofplants, a method to treat such seeds and plants, and soil with alow-concentration microalgae-based composition, in a dried or liquidsolution form was developed. Microalgae can be grown in heterotrophic,mixotrophic, and phototrophic conditions. Culturing microalgae inheterotrophic conditions comprises supplying organic carbon (e.g.,acetic acid, acetate, glucose) to cells in an aqueous culture mediumcomprising trace metals and nutrients (e.g., nitrogen, phosphorus).Culturing microalgae in mixotrophic conditions comprises supplying lightand organic carbon (e.g., acetic acid, acetate, glucose) to cells in anaqueous culture medium comprising trace metals and nutrients (e.g.,nitrogen, phosphorus). Culturing microalgae in phototrophic conditionscomprises supplying light and inorganic carbon (e.g., carbon dioxide) tocells in an aqueous culture medium comprising trace metals and nutrients(e.g., nitrogen, phosphorus).

In some embodiments, the microalgae cells can be harvested from aculture and used as whole cells in a liquid composition for applicationto seeds and plants, while in other embodiments the harvested microalgaecells can be subjected to downstream processing and the resultingbiomass or extract can be used in a dried composition (e.g., powder,pellet) or a liquid composition (e.g., suspension, solution) forapplication to plants, soil, or a combination thereof. Non-limitingexamples of downstream processing comprise: drying the cells, lysing thecells, and subjecting the harvested cells to a solvent or supercriticalcarbon dioxide extraction process to isolate an oil or protein. In someembodiments, the extracted (i.e., residual) biomass remaining from anextraction process can be used alone or in combination with othermicroalgae or extracts in a liquid composition for application toplants, soil, or a combination thereof. By subjecting the microalgae toan extraction process the resulting biomass is transformed from anatural whole state to a lysed condition where the cell is missing asignificant amount of the natural components, thus differentiating theextracted microalgae biomass from that which is found in nature.Excreted products from the microalgae can also be isolated from amicroalgae culture using downstream processing methods.

In some embodiments, microalgae can be the predominant active ingredientsource in the composition. In some embodiments, the microalgaepopulation of the composition can include whole biomass, substantiallyextracted biomass, excreted products (e.g., EPS), extracted protein, orextracted oil. In some embodiments, microalgae include at least 99% ofthe active ingredient sources of the composition.

In some embodiments, microalgae include at least 70% of theactive ingredient sources of the composition. In some embodiments,microalgae include at least 60% of the active ingredient sources of thecomposition. In some embodiments, microalgae include at least 50% of theactive ingredient sources of the composition. In some embodiments,microalgae include at least 40% of the active ingredient sources of thecomposition.

In some embodiments,microalgae include at least 5% of the active ingredient sources of thecomposition. In some embodiments, microalgae include at least 1% of theactive ingredient sources of the composition. In some embodiments, thecomposition lacks any detectable amount of any other active ingredientsource other than microalgae.

In some embodiments,microalgae biomass, excreted products, or extracts can also be mixedwith fish oil. Non-limiting examples of other plants, macroalgae,seaweeds, and kelp fractions that can be combined with microalgae cellscan include species of Lemna, Gracilaria, Kappaphycus, Ascophyllum,Macrocystis, Fucus, Laminaria, Sargassum, Turbinaria, and Durvilea. Infurther embodiments, the extracts can comprise, but are not limited to,liquid extract from a species of Kappaphycus. In some embodiments, theextracts can include 50% or less by volume of the composition. In someembodiments, the extracts can include 40% or less by volume of thecomposition. In some embodiments, the extracts can include 30% or lessby volume of the composition. In some embodiments, the extracts caninclude 20% or less by volume of the composition. In some embodiments,the extracts can include 10% or less by volume of the composition. Insome embodiments, the extracts can include 5% or less by volume of thecomposition.

Analysis of the DNA sequence of the strain of Chlorella sp. described inthe specification was done in the NCBI 18s rDNA reference database atthe Culture Collection of Algae at the University of Cologne (CCAC)showed substantial similarity (i.e., greater than 95%) with multipleknown strains of Chlorella and Micractinium. Those of skill in the artwill recognize that Chlorella and Micractinium appear closely related inmany taxonomic classification trees for microalgae, and strains andspecies may be re-classified from time to time. Thus, for referencesthroughout the instant specification for Chlorella sp., it is recognizedthat microalgae strains in related taxonomic classifications withsimilar characteristics to the reference Chlorella sp. strain wouldreasonably be expected to produce similar results.

Additionally, taxonomic classification has also been in flux fororganisms in the genus Schizochytrium. Some organisms previouslyclassified as Schizochytrium have been reclassified as Aurantiochytrium,Thraustochytrium, or Oblongichytrium. See Yokoyama et al. Taxonomicrearrangement of the genus Schizochytrium [sensu lato] based onmorphology, chemotaxonomic characteristics, and 18S rRNA gene phylogeny(Thrausochytriaceae, Labyrinthulomycetes): emendation for Schizochytriumand erection of Aurantiochytrium and Oblongichytrium gen. nov.Mycoscience (2007) 48:199-211. Those of skill in the art will recognizethat Schizochytrium, Aurantiochytrium, Thraustochytrium, andOblongichytrium appear closely related in many taxonomic classificationtrees for microalgae, and strains and species may be re-classified fromtime to time. Thus, for references throughout the instant specificationfor Schizochytrium, it is recognized that microalgae strains in relatedtaxonomic classifications with similar characteristics to Schizochytriumwould reasonably be expected to produce similar results.

By artificially controlling aspects of the microalgae culturing processsuch as the organic carbon feed (e.g., acetic acid, acetate), oxygenlevels, pH, and light, the culturing process differs from the culturingprocess that microalgae experiences in nature. In addition tocontrolling various aspects of the culturing process, intervention byhuman operators or automated systems occurs during the non-axenicmixotrophic culturing of microalgae through contamination controlmethods to prevent the microalgae from being overrun and outcompeted bycontaminating organisms (e.g., fungi, bacteria). Contamination controlmethods for microalgae cultures are known in the art and such suitablecontamination control methods for non-axenic mixotrophic microalgaecultures are disclosed in W02014/074769A2 (Ganuza, et al.), herebyincorporated by reference. By intervening in the microalgae culturingprocess, the impact of the contaminating microorganisms can be mitigatedby suppressing the proliferation of containing organism populations andthe effect on the microalgal cells (e.g., lysing, infection, death,clumping). Thus, through artificial control of aspects of the culturingprocess and intervening in the culturing process with contaminationcontrol methods, the microalgae culture produced as a whole and used inthe described inventive compositions differs from the culture thatresults from a microalgae culturing process that occurs in nature.

During the mixotrophic culturing process the microalgae culture can alsoinclude cell debris and compounds excreted from the microalgae cellsinto the culture medium. The output of the microalgae mixotrophicculturing process provides the active ingredient for composition that isapplied to plants for improving yield and quality without separateaddition to or supplementation of the composition with other activeingredients not found in the mixotrophic microalgae whole cells andaccompanying culture medium from the mixotrophic culturing process suchas, but not limited to: microalgae extracts, macroalgae, macroalgaeextracts, liquid fertilizers, granular fertilizers, mineral complexes(e.g., calcium, sodium, zinc, manganese, cobalt, silicon), fungi,bacteria, nematodes, protozoa, digestate solids, chemicals (e.g.,ethanolamine, borax, boric acid), humic acid, nitrogen and nitrogenderivatives, phosphorus rock, pesticides, herbicides, insecticides,enzymes, plant fiber (e.g., coconut fiber).

In some embodiments, the microalgae can be previously frozen and thawedbefore inclusion in the liquid composition. In some embodiments, themicroalgae may not have been subjected to a previous freezing or thawingprocess. In some embodiments, the microalgae whole cells have not beensubjected to a drying process. The cell walls of the microalgae of thecomposition have not been lysed or disrupted, and the microalgae cellshave not been subjected to an extraction process or process thatpulverizes the cells. The microalgae whole cells are not subjected to apurification process for isolating the microalgae whole cells from theaccompanying constituents of the culturing process (e.g., tracenutrients, residual organic carbon, bacteria, cell debris, cellexcretions), and thus the whole output from the microalgae culturingprocess comprising whole microalgae cells, culture medium, cellexcretions, cell debris, bacteria, residual organic carbon, and tracenutrients, is used in the liquid composition for application to plants.In some embodiments, the microalgae whole cells and the accompanyingconstituents of the culturing process are concentrated in thecomposition. In some embodiments, the microalgae whole cells and theaccompanying constituents of the culturing process are diluted in thecomposition to a low concentration. The microalgae whole cells of thecomposition are not fossilized. In some embodiments, the microalgaewhole cells are not maintained in a viable state in the composition forcontinued growth after the method of using the composition in a soil orfoliar application. In some embodiments, the microalgae base compositioncan be biologically inactive after the composition is prepared. In someembodiments, the microalgae base composition can be substantiallybiologically inactive after the composition is prepared. In someembodiments, the microalgae base composition can increase in biologicalactivity after the prepared composition is exposed to air.

In some embodiments, a liquid composition can include low concentrationsof bacteria contributing to the solids percentage of the composition inaddition to the microalgae cells. Examples of bacteria found innon-axenic mixotrophic conditions can be found in W02014/074769A2(Ganuza, et al.), hereby incorporated by reference. A live bacteriacount can be determined using methods known in the art such as platecounts, plates counts using Petrifilm available from 3M (St. Paul,Minn.), spectrophotometric (turbidimetric) measurements, visualcomparison of turbidity with a known standard, direct cell counts undera microscope, cell mass determination, and measurement of cellularactivity. Live bacteria counts in a non-axenic mixotrophic microalgaeculture can range from I0⁴ to I0⁹ CFU/mL, and can depend oncontamination control measures taken during the culturing of themicroalgae. The level of bacteria in the composition can be determinedby an aerobic plate count which quantifies aerobic colony forming units(CFU) in a designated volume. In some embodiments, the compositionincludes an aerobic plate count of 40,000-400,000 CFU/mL. In someembodiments, the composition includes an aerobic plate count of40,000-100,000 CFU/mL. In some embodiments, the composition includes anaerobic plate count of 100,000-200,000 CFU/mL. In some embodiments, thecomposition includes an aerobic plate count of 200,000-300,000 CFU/mL.In some embodiments, the composition includes an aerobic plate count of300,000-400,000 CFU/mL.

In some embodiments, the microalgae based composition can besupplemented with a supplemental nutrient such as nitrogen, phosphorus,or potassium to increase the levels within the composition to at least1% of the total composition (i.e., addition of N, P, or K to increaselevels at least 1-0-0, 0-1-0, 0-0-1, or combinations thereof). In someembodiments, the microalgae composition can be supplemented withnutrients such as, but not limited to, calcium, magnesium, silicon,sulfur, iron, manganese, zinc, copper, boron, molybdenum, chlorine,sodium, aluminum, vanadium, nickel, cerium, dysprosium, erbium,europium, gadolinium, holmium, lanthanum, lutetium, neodymium,praseodymium, promethium, samarium, scandium, terbium, thulium,ytterbium, and yttrium. In some embodiments, the supplemented nutrientis not uptaken, chelated, or absorbed by the microalgae. In someembodiments, the concentration of the supplemental nutrient can include1-50 g per 100 g of the composition.

A liquid composition comprising microalgae can be stabilized by heatingand cooling in a pasteurization process. As shown in the Examples, theinventors found that the active ingredients of the microalgae basedcomposition maintained effectiveness in at least one characteristic of aplant after being subjected to the heating and cooling of apasteurization process. In other embodiments, liquid compositions withwhole cells or processed cells (e.g., dried, lysed, extracted) ofmicroalgae cells may not need to be stabilized by pasteurization. Forexample, microalgae cells that have been processed, such as by drying,lysing, and extraction, or extracts can include such low levels ofbacteria that a liquid composition can remain stable without beingsubjected to the heating and cooling of a pasteurization process.

In some embodiments, the composition can be heated to a temperature inthe range of 50-130° C. In some embodiments, the composition can beheated to a temperature in the range of 55-65° C.

After the step of heating or subjecting the liquid composition to hightemperatures is complete, the compositions can be cooled at any rate toa temperature that is safe to work with. In one non-limiting embodiment,the composition can be cooled to a temperature in the range of 35-45° C.In some embodiments, the composition can be cooled to a temperature inthe range of 36-44° C. In some embodiments, the composition can becooled to a temperature in the range of 37-43° C. In some embodiments,the composition can be cooled to a temperature in the range of 38-42° C.In some embodiments, the composition can be cooled to a temperature inthe range of 39-41° C. In further embodiments, the pasteurizationprocess can be part of a continuous production process that alsoinvolves packaging, and thus the liquid composition can be packaged(e.g., bottled) directly after the heating or high temperature stagewithout a cooling step.

In some embodiments, the composition can include 5-30% solids by weightof microalgae cells (i.e., 5-30 g of microalgae cells/100 mL of theliquid composition). In some embodiments, the composition can include5-20% solids by weight of microalgae cells. In some embodiments, thecomposition can include 5-15% solids by weight of microalgae cells.

In some embodiments,the composition can include less than 0.9% by weight of microalgaebiomass or extracts. In some embodiments, the composition can includeless than 0.8% by weight of microalgae biomass or extracts.

Insome embodiments, the composition can include less than 0.5% by weightof microalgae biomass or extracts. In some embodiments, the compositioncan include less than 0.4% by weight of microalgae biomass or extracts.In some embodiments, the composition can include less than 0.3% byweight of microalgae biomass or extracts. In some embodiments, thecomposition can include less than 0.2% by weight of microalgae biomassor extracts. In some embodiments, the composition can include less than0.1% by weight of microalgae biomass or extracts. In some embodiments,the composition can include at least 0.0001% by weight of microalgaebiomass or extracts.

In some embodiments, the composition caninclude at least 0.1% by weight of microalgae biomass or extracts. Insome embodiments, the composition can include 0.0001-1% by weight ofmicroalgae biomass or extracts. In some embodiments, the composition caninclude 0.0001-0.001% by weight of microalgae biomass or extracts. Insome embodiments, the composition can include 0.001-0.01% by weight ofmicroalgae biomass or extracts. In some embodiments, the composition caninclude 0.01-0.1% by weight of microalgae biomass or extracts. In someembodiments, the composition can include 0.1-1% by weight of microalgaebiomass or extracts.

In some embodiments, an application concentration of 0.1% of microalgaebiomass or extract equates to 0.04 g of microalgae biomass or extract in40 mL of a composition. While the desired application concentration to aplant can be 0.1% of microalgae biomass or extract, the composition canbe packaged as a 10% concentration (0.4 mL in 40 mL of a composition).Thus, a desired application concentration of 0.1% would require 6,000 mLof the 10% microalgae biomass or extract in the 100 gallons of waterapplied to the assumption of 15,000 plants in an acre, which isequivalent to an application rate of about 1.585 gallons per acre. Insome embodiments, a desired application concentration of 0.01% ofmicroalgae biomass or extract using a 10% concentration compositionequates to an application rate of about 0.159 gallons per acre. In someembodiments, a desired application concentration of 0.001% of microalgaebiomass or extract using a 10% concentration composition equates to anapplication rate of about 0.016 gallons per acre. In some embodiments, adesired application concentration of 0.0001% of microalgae biomass orextract using a 10% concentration composition equates to an applicationrate of about 0.002 gallons per acre.

In another non-limiting embodiment, correlating the application of themicroalgae biomass or extract on a per plant basis using the assumptionof 15,000 plants per acre, the composition application rate of 1 gallonper acre is equal to about 0.25 mL per plant=0.025 g per plant=25 mg ofmicroalgae biomass or extract per plant. The water requirementassumption of 100 gallons per acre is equal to about 35 mL of water perplant. Therefore, 0.025 g of microalgae biomass or extract in 35 mL ofwater is equal to about 0.071 g of microalgae biomass or extract per 100mL of composition equates to about a 0.07% application concentration. Insome embodiments, the microalgae biomass or extract based compositioncan be applied at a rate in a range as low as about 0.001-10 gallons peracre, or as high as up to 150 gallons per acre.

In some of the embodiments and Examples below, the applications wereperformed using a 10% solids solution by weight microalgae composition.For greenhouse trials, the rates vary and essentially refer to how muchvolume of the 10% solids solution was added in a given volume of water(e.g. 9 ml/gal-150 ml/gal). For field trials, the rates are indicated ingal/acre and the amount of carrier water would be determined accordingto user preference. For field trials, the application rate may rangebetween 0.25 gal/acre-2 gal/acre. For example, in the greenhouse trialwhere the application rate is 9 ml/gal, the microalgae composition wouldcontain 0.95 g of microalgae/gal and where the application rate is 150ml/gal, the microalgae composition would contain 15 g of microalgae/gal.In the field trials, where the application rate of the microalgaecomposition is 0.25 gal/acre, the equivalent expressed in total grams ofsolid microalgae would be 100 g microalgae/acre; where the applicationrate of the microalgae composition is 0.5 gal/acre, the equivalentexpressed in total grams of solid microalgae would be 200 gmicroalgae/acre; where the application rate of the microalgaecomposition is 1.0 gal/acre, the equivalent expressed in total grams ofsolid microalgae would be 400 g microalgae/acre; and where theapplication rate of the microalgae composition is 2.0 gal/acre, theequivalent expressed in total grams of solid microalgae would be 800 gmicroalgae/acre.

Overall, as shown in the embodiments and Examples below, the microalgaecomposition may comprise between 0.95 g-15 g of microalgae per gallon,as it is common practice for growers to use between 100-250 gallons ofliquid carrier volume/acre. It should be clearly understood, however,that modifications to the amount of microalgae per gallon may beadjusted upwardly or downwardly to compensate for greater than 250gallons of liquid carrier volume/acre or less than 100 gallons of liquidcarrier volume/acre.

In some embodiments, stabilizing means that are not active regarding theimprovement of plant germination, emergence, maturation, quality, andyield, but instead aid in stabilizing the composition can be added toprevent the proliferation of unwanted microorganisms (e.g., yeast, mold)and prolong shelf life. Such inactive but stabilizing means can includean acid, such as but not limited to phosphoric acid or citric acid, anda yeast and mold inhibitor, such as but not limited to potassiumsorbate.

As shown in FIG. 7, eight weeks after transplanting, Red Merlinstrawberries were harvested and assessed for brix at the time ofharvest. Increases in brix were observed but were low overall as theberries were all on the lower end of the spectrum for ripe berries(<7%). Compared to standard practice, the lowest application rate of alltreatments (0.3 gal/A) showed a 2% increase. Compared to theseaweed-based commercial reference, advantages for all treatments weregreater (3-7%) but the rate response was not as clear.

Portola strawberries were harvested on eight occasions between 12 and 24weeks after transplanting and assessed for % brix at the time ofharvest. Fifteen weeks after transplanting, berries were harvested andstored in cold storage for 5 days and assessed for % brix. Brix at thetime of harvest was variable for treatments compared to the control. Asshown in FIGS. 8-9, the combination 25% Chlorella: 75% HS399 wholebiomass (WB) microalgae composition (0.25 gal/A) showed an advantageover standard practice in 4 of 8 harvests (2-7%). The PHYCOTERRA®Chlorella microalgae composition (0.5 gal/A) and the OMRI certifiedTERRENE® Chlorella pasteurized at 90° C. microalgae composition (0.25gal/A) showed an advantage in only 3 of 8 harvests compared to standardpractice (6-8% and 4-10%, respectively). Advantages were more seldomcompared to the seaweed-based commercial reference. The Aurantiochytriumacetophilum HS399 whole biomass (WB) microalgae composition (0.25 gal/A)showed an advantage over the seaweed commercial reference in 4 of 8harvests (2-5%). The PHYCOTERRA® Chlorella microalgae composition (0.5gal/A) showed an advantage over the commercial reference (4%) in 3 of 8harvests. For the post-harvest brix, as shown in FIG. 10, thePHYCOTERRA® Chlorella microalgae composition (0.5 gal/A) showed thelargest advantage over standard practice (8%). The Aurantiochytriumacetophilum HS399 washed whole biomass (WB washed) microalgaecomposition and the combination 25% Chlorella: 75% HS399 whole biomass(WB) microalgae composition also had advantages at both rates (3-5%).Only the PHYCOTERRA® Chlorella microalgae composition (0.5 gal/A) had anadvantage over the seaweed-based commercial reference (4%).

Allplots received standard local fertigation practice, including NEPTUNE'SHARVEST fertilizer and NFORCE fertilizer. A control was added withstandard local fertigation practice plus 4 applications of amicrobial-based commercial reference product that is standard to thislocation. Treatments included two versions of an OMRI certifiedChlorella microalgae composition that differ by pasteurizationtemperature (the OMRI certified TERRENE® Chlorella pasteurized at 65° C.microalgae composition and the OMRI certified TERRENE® Chlorellapasteurized at 90° C. microalgae composition), each tested alone andeach tested in combination with the microbial-based commercialreference. Strawberry plants (frigo) were transplanted to the field inJune 2017, according to local commercial practice. The first productapplication was via drip irrigation at the time of transplanting andthen every 14 days afterward through to final harvest. The untreatedcontrol received the same amount of carrier water as other treatments atthe time of each product application. The microalgae compositions wereshaken well before application and agitated while in the chemigationtank in order to prevent solids from settling. Berries were harvestedaccording to local commercial schedule (twice per week during fruitingseason). The timing of the commercial reference applications were onceat the time of planting (6/20), once 14-21 days after planting (7/5),once in late July/early August (7/31) and the last in early September(9/11). All plots were managed according to the local standard practice(see Study Parameters below).

At 11, 14 and 18 weeks after transplanting, berries were harvested andstored in cold storage for 6 days then assessed for % brix after thestorage period. Referring to FIG. 11, for the first and second holdingtest, most treatments had lower brix than standard practice. Theexception was the combination Commercial Reference+OMRI certifiedTERRENE® Chlorella pasteurized at 65° C. microalgae composition, whichhad a 3% advantage. For the final holding test, the combination ofCommercial Reference+OMRI certified TERRENE® Chlorella pasteurized at90° C. microalgae composition, the OMRI certified TERRENE® Chlorellapasteurized at 65° C. microalgae composition (0.5 gal/A) alone, and bothrates of the OMRI certified TERRENE® Chlorella pasteurized at 90° C.microalgae composition alone had 2-4% advantage over standard practice.By this time, the trial was beginning to be affected by a fungalinfection that spread across the entire ranch which may have affectedberry quality and given the products more of an advantage. Compared tothe commercial reference, advantages were observed for severaltreatments for the first two holding tests, with the highest being thecombination Commercial Reference+OMRI certified TERRENE® Chlorellapasteurized at 65° C. microalgae composition (7%).

A trial was conducted on bell peppers (var. Capsicum annuum Ace) in agreenhouse in Gilbert, Ariz. to evaluate performance of the PHYCOTERRA®Chlorella microalgae composition on bell pepper sweetness. Capsicumannuum Ace is a bell pepper cultivar grown for both mature green and redripe fruit in controlled environments. This variety was grown from seedto yield in a horticultural greenhouse and the PHYCOTERRA® Chlorellamicroalgae composition treatments were administered via manual drench tothe soil every 14 days starting at the time of transplanting. Thepurpose of this experiment was to test whether increasing rates ofPHYCOTERRA® Chlorella microalgae composition can establish an optimalapplication rate to increase percent brix.

Replicates were irrigated with treatments bi-weekly until harvest. Datawas collected on fruits within the guidelines of USDA marketable bellpepper standards. Mature green fruit was harvested once a week for 3weeks. Red ripe fruit was harvested daily for three weeks. Fruits werejuiced, and percent brix was recorded using a HI 96801 refractometer.The metric described was percent brix, which is a measure of totaldissolved solids in the juice of the fruit and which equates todissolved sugars and sweetness.

Application rates of the PHYCOTERRA® Chlorella microalgae composition asapplied for red ripe and mature green bell peppers were as detailed inTable 11 below. Raw data is included in the table shown in Table 12below.

Replicate plants were given a slow release fertilizer (OSMOTCOTEfertilizer) and irrigated with reverse osmosis (RO) water. Every twoweeks replicates were treated with corresponding treatment diluted incity water. At the end of the trial, replicate plant fruits wereharvested as either mature green or red ripe. Brix measurements weretaken only on qualifying fruit based on USDA standards. Fruits werejuiced, and percent brix was taken on individual fruits of eachreplicate plant. This trial ran for 144 days from seeding to finalharvest.

Mature green bell peppers were harvested once a week for three weeks.USDA standard marketable fruits were juiced, percent brix was taken onindividual fruits and percent was recorded. Table 12 below shows rawvalues for percent brix for each treatment and percent change oftreatments relative to the control. The 9 ml/gal application rateresulted in a 17% increase in brix of green peppers for the earliestharvest, but no other benefits were observed. FIG. 13 shows results fromthe first green bell pepper harvest where bell peppers treated with 9ml/gal of PHYCOTERRA® Chlorella microalgae composition demonstrated anumerical advantage over the control. FIG. 14 shows the results from thesecond green bell pepper harvest and FIG. 15 shows the results from thethird green pepper harvest where no advantage was shown over the controlin either harvest.

Red ripe bell peppers were harvested daily over three-week intervals.USDA standard marketable fruit were juiced, and percent brix was takenon individual fruit. The average percent brix of all fruits pertreatment was taken over three one-week intervals. Table 13 below showsraw values of percent brix and percent change of treatments relative tothe control. The majority of the application rates resulted in brixincreases in 2 of 3 harvest periods. The 75 mL/gal application increasedBrix for red peppers in all 3 harvest periods at 7-14%.
